Aiming at the problem to make a balance between security and economy of power system operation, the optimal power flow models suitable for analysis and calculation of power system, considering multistate and multi-constraint, used in adjusting the generation schedule were constructed, the nonlinear optimal power flow algorithms based on interior point method were studied, a software developed by Visual C ++ 6.0 for generation cost on-line system was presented. The total framework, the module division and the function characteristic of software development were described in detail. The result indicates that the software can realize e-conomical distribution of load deviation and the lowest purchase cost based on safe and stable operation of power system.
